Now that the table view has a cursor, we can distinguish it from the
selected cells. Draw the cells with a nice variant of the selection
color as background.
Views now have a cursor index (retrievable via cursor_index()) which
is separate from the selection.
Until now, we've been using the first entry in the selection as
"the cursor", which gets messy whenever you want to select more than
one index in the model.
When setting the cursor, the selection is implicitly updated as well
to maintain the old behavior (for the most part.)
Going forward, this will make it much easier to implement things like
shift-select (extend selection from cursor) and such. :^)
A view can now be told to move its cursor in one of multiple directions
as specified by the CursorMovement enum.
View subclasses can override move_cursor(CursorMovement) to implement
their own cursor behavior. By default, AbstractView::move_cursor() is
a no-op.
This patch improves code sharing between TableView and TreeView. :^)
For some weird reason the C++ standard considers char, signed char and
unsigned char *three* different types. On the other hand int is just an
alias for signed int, meaning that int, signed int and unsigned int are
just *two* different types.

Do not fill the backing store mismatch area with the solid window
color if the window is transparent. This caused some minor flicker
when such a window is e.g. snapped to the left/right or maximized.
Before, we had about these occurrence counts:
COPY: 13 without, 33 with
MOVE: 12 without, 28 with
Clearly, 'with' was the preferred way. However, this introduced double-semicolons
all over the place, and caused some warnings to trigger.
This patch *forces* the usage of a semi-colon when calling the macro,
by removing the semi-colon within the macro. (And thus also gets rid
of the double-semicolon.)
It wasn't used anywhere.
Also, if it were used, then it should have been marked AK_NONCOPYABLE().
Or even more cleanly, it should use a RefPtr<> or OwnPtr<> instead of
a 'naked' pointer. And because I didn't want to impose any such decision
on a possible future use case that we don't even know, I just removed
that unused feature.
Now we have an actual stream implementation that can read arbitrary
(dynamic codes aren't supported yet) deflate encoded data. Even if
the blocks are really large.
And all of that happens with a single buffer of 32KiB. DEFLATE is
amazing!
If both the row and column headers are visible, we now also show a
button in the top left corner. This avoids the headers overlapping
each other when you scroll the contents.
In the future, this could be hooked up to a "select all" action.
